However, Mr Harold told talkRADIO’s Mike Graham: “There is a stereotype, of course there is, but it is what we have all seen through documentaries or what I have witnessed myself.

“Under the “non-upper class” list, we have got things like British Airways – I feel sorry for them – and Windsor.

“I am a bit confused at that but let’s not tell the Royal family. Let’s keep that one quiet.

“I don’t quite know how they have come up with this.”

'A PR stunt'

Mr Harold added that the mention of “posh” as “non-upper class” was "annoying".

He said “posh” refers to 'port out, starboard home' – which was the most comfortable accommodation on the ships travelling between England and India, port being the left side of the ship and starboard the right. That origin story is unproven and disputed by some.

“The other thing that annoyed me is that they are saying the word ‘posh’ is no longer upper class,” Mr Harold said.
